USER INSTRUCTIONS

AUTOMATIC CHARGING AND BATTERY STATUS MONITORING:

Battery Tender® chargers are completely automatic and may be left
connected to both AC power and to the battery that it is charging for long
periods of time. The charger output power, voltage, and current depends
on the condition of the battery it is charging.

ATTENTION: The Battery Tender® CHARGER HAS A SPARK FREE
CIRCUITRY. The output alligator clips will not spark when they are touched

together. The Battery Tender® charger will not produce an output voltage
until it senses at least 2-3 volts from the battery. It must be connected to a
battery with the correct polarity before it will start charging a battery.
Therefore, if you plug the AC power cord into an AC power outlet, and if the
output alligator clips are not connected to a battery, and if you touch the
alligator clips together, there will be no electrical spark.

REVERSE POLARITY PROTECTION: The battery charger is protected
against any damage due to the DC output leads being connected to the
opposite polarity battery post. ELECTRICAL SPARKING will occur when
the clips are connected in this way.

NOTE:
THE OUTPUT CLIPS MUST BE CONNECTED TO A BATTERY BEFORE
THE CHARGER CAN PRODUCE AN OUTPUT VOLTAGE, EXCEPT
WHEN IN THE DC OUTPUT MODE

WORKING WITH A DEAD BATTERY OR A BATTERY WITH A VERY
LOW VOLTAGE:

If you try to charge a dead battery either lead-acid (standard) or AGM
having a voltage between 2-3 volts (8V for Li-Ion), the Battery Tender®
charger will not start. An internal safety circuit prevents the charger from
generating any output voltage unless it senses at least 3 volts (8V for Li­Ion) at the charger output.

NOTE:
If a 12-volt, lead-Acid (standard) battery has an output voltage of less than
9 volts when it is at rest, when it is neither being charged nor supplying
electrical current to an external load, there is a good chance that the
battery is defective. As a frame of reference, a fully charged 12-volt, lead­Acid battery will have a rest-state, no-load voltage of approximately 12.9
volts. A fully discharged 12-volt, lead-acid battery will have a rest-state, no­load voltage of approximately 11.4 volts. That means that a voltage change
of only 1.5 volts represents the full range of charge 0% to 100% on a 12­Volt, lead-acid battery. Depending on the manufacturer, and the age of the
battery, the specific voltages will vary by a few tenths of a volt, but the 1.5­volt range will still be a good indicator of the battery charge %.

CHARGER FUNCTIONS/MODES

OUTPUT POWER MODE DETAILS

1. 1.25A CHARGE: This mode will charge and maintain a 12 volt

battery for long periods of time. This function is completely
automatic and will never over charger your battery. The charger
output power, voltage, and current depends on the condition of the
battery it is charging.

2. 20A BOOST: This mode will Boost the battery at a maximum rate
of 20Amps until the battery voltage increases to approximately 14
volts. When the battery voltage reaches the target, the charger
then exits the Boost mode. Li-Ion batteries are not supported in this
mode.

3. 75A ENGINE START: This mode will first use 10Amps to
increase the battery voltage to at least 10.5 volts. Once the
battery reaches 10.5 volts, the charger is ready for an engine
start. If the voltage is less than 9 volts, the charger assumes
the key has been turned. Now the charger applies up to
75Amps to assist starting the engine. After five (5) seconds,
the charger will stop the 75Amp current and go into cool down
mode for two (2) minutes. Li-Ion batteries are not supported in
this mode.

4. POWER SUPPLY: This mode provides low voltage DC current
of one (1) Amp at 13 volts. The Power Supply function is for
use as only a memory saver when changing out a battery.

5. WARNING/ERROR LED: There are safety timers built into the
charger which vary depending on which battery type you have
selected. These timers will prevent a bad battery from being
over charged if it does not reach optimum voltage within these
time frames. Have your battery checked if this occurs. This
LED also indicates if the charger alligator clips are connected
backwards to the battery (reverse polarity). Lastly, if this LED is
blinking, this is the indication the WiFi is off. Refer to the WiFI
section to turn it back on.

CHARGER OPERATION

1) POWERING UP: When you first plug the charger into a power
outlet, all of the LED’s and battery level lights will illuminate for

about two (2) seconds.

connected to the battery to start the charge cycle. When the clips
are connected, the battery level indicator will illuminate to show the
state of charge. To start the charge cycle, press the charge select
button or wait four (4) seconds. The charge LED will turn on solid
and the battery level lights will begin to illuminate from left to right
indicating a charge is in progress. All the battery level lights will be
on solid when the battery is fully charged and in maintenance
mode.

7) 75A ENGINE START: To start the engine start cycle, press the
function select button until the engine start LED is blinking.
Connect the alligator clips to the battery to begin the engine start
cycle. In order to begin the engine start mode, the battery voltage
needs to be above 10.5 volts. If this is not the case, the charger will

enter Boost Mode (All battery LEDs blink).

6) 20A BOOST: To start the boost cycle press the function select
button until the 20A Boost led is illuminated. Connect the alligator
clips to the battery and the LED’s in the battery level indicator will
illuminate. Then press the boost select button and the LED will turn
solid to begin the boost cycle. The five (5) left battery level lights
will begin to illuminate from left to right until they are all solid and
the battery has reached 14 volts. The boost cycle will then shut off.

Once the battery has reached 10.5 volts, an engine start can be
performed. At this point, the Battery LEDs will light up in sequence
from left to right.

8) POWER SUPPLY: To start the Power Supply mode, press the
function select button until the Power Supply LED is illuminated.
Connect the alligator clips to the battery. Then press the power
supply button, the power supply LED will then turn solid green

while also turning the power supply on.

9) WiFi: When AC power is applied to the charger the WiFi will
automatically turn itself on. If you wish to turn the WiFi off, hold the
battery select button down for ten (10) seconds.
The WARNING/ERROR LED will blink to indicate the WiFi is off.
To turn the WiFi back on, simply press the select button down for

ten (10) seconds.
